I visited my sibling a few months back when winter season was almost ending, however it was still cold, plus we had to stay most of the time indoors.
Around the same time, his heating system had given up on his because it was aged plus ancient, and he had tried everything, including emergency HVAC services, however no effort seemed to help restore the unit to its former glory. On the advice of his trusted HVAC specialist, he opted to get a few portable boilers to use in the rooms that were most tied up before he could invest in a suitable heating system later on. This meant we had to wear moderate clothing inside the cabin since there was only so much that the portable boilers could do at the time… When I talked to my sibling, it seemed he had ignored the heating system issue before. For a few months before I visited, he said he would hear spooky sounds coming from the heating system direction. However, it never crossed his mind that his heating system was responsible for this. Many times he assumed that someone was playing disturbing music late at night. The screeching plus high-pitched noises were coming from his heater. It was so clear that the heating system needed some lubrication back then to spare it the excess wear plus tear that we could now see! Probably if he had done this earlier, the unit would have served his a few more years before needing to be updated… Nonetheless, there was no significant loss since the unit had been in the cabin for more than two decades when my sibling first obtained his house. It was about time he got a new heating unit.
